19 Claims. 1

The invention relates to a novel and improved power driven ironer of the type wherein the work to be ironed is advanced around a centrally located heated roll, and between it and a plurality of cooperating pressure rolls, usually having padding thereon, and biased into contact with the heated roll.

An object of the invention is to provide novel and improved means for controlling the application and relaxation of the pressure of the outer rolls against the heated roll. For convenience of reference, and avoidance of confusion, the inner heated roll will be hereinafter termed the main roll, and the outer padded rolls will be termed the ironing rolls.

A further object of the invention is to provide novel and improved burner equalizer means, disposable within the main roll, for evenly and efficiently heating said main roll, so as to avoid localized hot points.

A further object of the invention is to provide fluid fuel burner means in combination with said main roll, wherein adequate capacity is provided for supplying secondary air to the burner.

A further object of the invention is to provide fluid fuel burner means in combination with the main roll, the construction being adapted to prevent access of flame flashbacks to the padding.

A further object of the invention is to provide roll heating means as defined in the three immediately preceding paragraphs wherein the primary air supply requires no blower.

A further object of the invention is to provide novel and improved bypass deflector means, in combination with the main roll and the ironing rolls whereby the ironed work pieces issuing from the rolls may be deflected, at will, either towards the front or the rear of the machine.

A further object of the invention is to provide a bank of novel stripper fingers, which are individually readily removable, movable, or replaceable.

Other objects and advantages will be apparent from a study of the following specification, in conjunction with the accompanying drawings, wherein:

Fig. 1 is a left side elevational view, with housing parts broken away to reveal internal structure, showing a gas heated roll type ironer embodying the present invention.

Fig. 2 is a to plan view of the ironer.

Fig. 3 is a detail view of a fragmentary portion of the stripper assembly, taken approximately on the line 33 of Fig. 1.

Fig. 4 is a sectional view, somewhat enlarged, taken on the line l-d of Fig. 3.

Fig. 5 is a fragmentary right side elevational View, with the housing partially broken away to reveal burner, burner supply, and control parts.

Fig. 6 is a fragmentary vertical sectional view through the left end of the main roll, taken on the line 6--6 of Fig. 2.

Fig. '7 is an enlarged fragmentary sectional detail showing one of the burner orifices.

Referring to the drawings, the apparatus now to be described is supported on a spaced pair of end frames H which carry therewithin a spaced pair of circular end heads l2 (Fig. 2). J ournaled in the end heads and end frames are two supporting idler rollers 53, one on each side, adapted to carry thereon the main roll it. For this purpose the said main roll has attached to each of its open ends (Fig. 6) a shouldered sleeve l5 each of which has a fixed rabbetted fit in its respective roll end. Each said sleeve G5 has a sleeved extension 56, such extension at each roll end resting on a respective pair of the rollers [3 above mentioned.

The main roll is driven counterclockwise (as viewed in Fig. l) by a roller link chain I! which engages an annular sprocket l8 (Fig. 6) fixed on the outer periphery of sleeve 55. Chain l'l passes over the top of sprocket I8, under a sprocket E9 on a ribbon roll 2fi,around a sprocket 28 on a front ribbon feed roll 24, down over a slack take-up idler sprocket 25, then engages a drive sprocket 26, up over the sprocket 2? of another ribbon roll 28, and finally under another sprocket 29 freely rotatable on a ribbon roll 3t and thence back on sprocket [8.

The ribbon rolls just mentioned, as well as others cooperating therewith, drive various sets of ribbons for movement of the Work, as will appear.

The chain drive sprocket 26 is driven from motor 3| through suitable controllable reduction gearing generally indicated by the letter R in Fig. 1, and such gearing is conventional. Variation in speed is achieved by manipulation of a shaft 32 having a handle Tia. located to extend through a housing 33, and having in conjunction therewith an indicator 34 carried on a rod 35 secured to a sleeve 36 threaded on shaft 32. Rotation of shaft 32 moves the sleeve 36 on the shaft, so as to cause indicator 35 to correspondingly move along scale means (not shown) at the slot in the housing through which the rod extends. The scale has suitable speed indicating markings thereon for the operators guidance.

As previously indicated, ironing of thework piece is-effected by introducing the piece between the main roll l4 and one or more (preferably a plurality) ironing rolls 31, five such rolls being shown distributed around and generally above a horizontal diametrical plane through the main roll axis. These ironing rolls have padding 38 thereon, and they are driven by means of a roller chain 39 secured around a sleeve on the right hand end of the main roll, there being a sprocket 48 on each ironing roll (Fig. 1) which engages said chain 39.

Since, as will appear, the ironing rolls are movable a limited distance towards and from the main roll, the teeth of sprockets so are made long enough to maintain driving connection with roller chain 3%} during such movement.

All ironing rolls are similarly constructed and controlled, so description of one will suflice for all. The ironing rolls 3? are supported on shafts id journaled in bearings Q5 slidable radially in slots. st in circular end heads 52, the bearings having guide slots 4'? which ride on the slot edges (Fig. 6). A threaded stud 48 is secured to each bearing, the stud being slidable through a block 39, there being a compression spring 55! between the block and an adjustable nut ti on a threaded portion of the stud so as to adjust spring pressure. An upper nut 52 provides an end stop for block movement under spring bias, when inward pressure on the block (as will be described) is released. The block #59 is pivotally carried between spaced links 53, hereinafter termed pressure links. At their outer ends the links carry thereebetween a roller 5 which is circumferentially movable through a limited arcuate track at the periphery of end heads 62. The track is formed by outer parallel arcuate strips 55 and 5d at both ends is thereafter secured by making suitable adjustments of the nuts 5i which compress the springs dt in the pressure link. The structure and arrangement of the pressure links, connecting links, and associated parts is such that a combined camming and toggle action is secured in applying pressure to the ironing rolls.

As previously indicated, chain ll provides the motive force for all rotating elements including the work-advancing ribbons. The feed ribbons 5? are of endless character, as is usual, rotating around driving roll 68 at the front (right side of Fig. i) and around a rear rod 59 adjacent the main roll i l. The upper stretch of ribbons ti is slid-ably supported on a feed table it, which is supported by the circular end heads l2, and by frame extensions H. The roll 53 is adjustably supported by bearings E2 in slots in the frame extension il. A smoothing or drag roll "it rides on ribbons 6? being generally upwardly displaceable in slots in brackets i l at opposed sides of table 16. I

A set of belts i5 is supported by rolls 2%, 3t, and a small rear tube or roll it, there being a slack take-up roller 5'! resting in vertically movthe circular end heads.

which are secured to the periphery of the end heads. The end heads are cut out at El (Fig. l) for this purpose.

The several shafts which support the respective rollers E i are interconnected by links 58 which permit the several pressure link units to be operated simultaneously to apply or relieve pressure between the ironing rolls and the main roll. For this purpose the rearmost pressure link is connected to one arm 6! of a toggle (Fig. l) ,the other arm 62 being of hell crank shape, and being fixed at its elbow on a cross rod 63 pivotally carried between the end frames ll. It will be apparent that downward foot pressure applied to the pedal portion 52a of arm 82 will move the toggle lin1-- age from the broken line position to the full line position of Fig. 1, thereby also moving the pressure links 53 clockwise from the broken line to the full line position, as shown by the lowest one on the left. In their full line position the links are applying maximum inward pressure radially on the ironing rolls. In such pressure position the toggle 65, 52 is maintainable in over-center position so that the operator can remove the foot from pedal 62a. The toggle is broken by another foot operated lever 64 which has an operating tip Eta which can be pressed upwardly against the under side of arm 52. Lever M is pivoted at t lb on the frame. When the toggle is thus broken a spring 65 returns the pressure links 53 to pressure-relaxed position, the lower end of the spring being connected to the frame, and the upper end to an adjustable link 63 on the second nearest roller 56.

It should be mentioned that there are duplicate pressure control linkages 53 on both ends of the ironing rolls, as well as duplicate toggles iii, 2, the shaft 53 being the means whereby operation of the foot pedal 62a operates the toggles and responsive elements on both sides. Even pressure able position on the lower stretch of belts 5. The weight of roller ll pulls the upper stretch of belts '55 into working contact with the lower periphery of main roll M. Below belts i5 is another set of belts '58 supported by roll 23 and a smaller roll,

tube, or rod it, there being a take-up roller 85 riding on the top of the lower stretch of belt '58. The various rolls mentioned in connection with the operation of the ribbons are supported on A set of tapes 8! runs between the ironing rolls 3'! and the main roll Hi, to prevent the work from curling up around the ironing rolls during the ironing operation. Tapes 8i pass under across member 32 at the rear and around a tube or roll 83 (Fig. 2) at the front, as well as over the tops of the ironing rolls. The roll 83 is mounted on a cross rod 81 extending between the end heads l2, which rod also carries the usual safety finger guard 85.

Path selector means is provided for optional routing of the work either towards the operator at the front, or towards a possible operator at the rear.

Referring to Fig. 1, the path selector comprises a transversely extending plate 83, pivotally supported at 8B and having pivoted thereto, at each side edge of the plate, an arm 9t which is adapted to be moved from the full line position to the broken line position of Fig. 1. For stop purposes the arm 96 has an end portion which engages behind an abutment ti on the bin or basket 92, as indicated in the full line position. In this position the workpiece travel is over the feed ribbon 6?, around the top of main roll Hi and between the main roll and the ironing rolls 3'5, between the belts i5 and the main roll, over roll 29, onto guide plate 88, down onto delivery ribbons l8, and rearwardly to a rear work-receiving table 93.

If the deflector plate is dropped to its lower position, the work proceeds as before until it feeds over ribbons '55 on roll 26, whereupon plate 8B deflects the work directly into bin 92.

S becomes-entangled inone orimore of thestrippers. Normally the entire stripper assembly must be removed. Each finger 94 is supported on a rod 95 pivotally supported on end heads 12, there being a-handle 96 on the rod for turning it when a finger is to be removed. As best seen in Fig. 4, rod 95 has flattened portions at each finger position, so'as to reduce the rod in diameter in one direction. Each finger has a collarportion 94a slotted to admit the flattened portion of the rod. When in operating position, the relation of the stripper, collar, and rod is as shown inl-Fig. 4. To remove a finger the rod 95 is turned'through 96 degrees whereupon the flattened rod portion is aligned with theslot in collar 94a so as to permit forward withdrawal of the finger.

The main roll is heated internally by a gas burner which issupplied with gas at one end. The burner consists of a pipe 97 (Fig. 6) having a plurality of rows or" orifices 98 in its upper wall, there being three rows in the present case. These orifices are counter-bored (Fig. '7) which reduces the likelihood that the flames, which are upwardly directed, will b blown away. The burner pipe is supported at each end by a bracket 9e, and at one end by a securing U-bolt illii (Figs. and 7). The ends of the roll iii are open to furnish a plenteous supply of secondary air so that no blower is required. The burner pipe is capped on its left end, and at its right end is in communication with a standard mixing device Edi to which the gas enters at i323 and the primary air at M3. The gas supply comes from the main through pipe I54 and to a dual valve housing 565, which has twovalves in series. The first valve is open only when a pilot burner N is lit, being controlled by a thermoresponsive element energized by the lighted burner. Pilot fuel is admitted through tube lfl'l, and expansive fluid pressure is effective through tube its on a bellows in the bay itiia so as to open the first valve. To start the pilot a plunger button iilii is depressed so as to hold said first valve open and permit fuel to iiow to the pilot burn-er which can then be lighted whereupon the first valve remains open and the plunger Hi9 can be released so that it automatically retracts.

The second valve in housing iii-l is electrically controlled by a solenoid in bay i352), said solenoid being'responsive to a switch iii) (Fig. 2) which, when energized, operates the solenoid to open the switch. The switch is operated by a lever Ma associated with the shaft or" the previously mentioned finger guard assembly, so that this second valve is open only when the finger guard is in protective position, the guard there by serving as an element in manual control.

The finger guard is accordingly first moved to safe position, so as to energize the solenoid for opening the second valve, the first valve having previously been opened as already described, and gas can now flow from pipe EM through the dual valve assembly to pipe ill to a standard thermostat H2 having a temperature selector and control knob NM. The thermostat is in communication through a capillary tube I i3 with a temperature responsive bulb H4 which is in motor which in the present embodiment is alsd controlled by switch llll so thatthe main roll may run unheated for any desired interval. A manual valve is usually provided inthe pilot line i iii, but is not here shown.

The flame equalizer for the burner will now be described. Extending through the burner pipe 9'6 from thecapped end is a pipe i2! which is flattened or-tapered towards the incominggas. This pipe 12! extends through only a fractional portion of the burner pipe, iuthis case approximately one-third the length of the burner. Certain adjustments can be made in both the relative length and diameter of the inner pipe [2! depending mainly on the length of the burner pipe 8?, the gas pressure, .etc. In an atmospheric-type burner such asthat here shown,. a dead-end or capped burnergives higher jets of flame near the capped end and I have found that a device such as pipe l2i serves to equalize the height oi the jets along the lengthof the burner. A solid rod with tapered end can be substituted for pipe [2 l An arched metal screen or grid I22 is carried by rods :23 above'the burner orifices and near theuppcr inner wall of main roll Hi. When the burner is lighted this screen becomes redhot and prevents incomplete combustion whichsometimes occurs as the fuel jets impinge on the inner roll surface.

in previous burner heated rolls of this type the ends of the roli, andespecially'the fuel supply end, are necked down or blocked to confine the flame, and as a result there was an inadequate supply of secondary air. Also in the prior construction it was customary to supply a blower in the primary air supply. By providing wide open main roll ends the present invention supplies ade uate secondary and avoids an excess of primary air usually resulting from the use of a blower. The escape of combustion products through a fine M4 at both ends of the roll (one being shown in Fig. 5) draws in an adequate supply of secondary air at the rolls ends. The rolls ends are carried out to the side frames, thereby eliminating the possibility that flash backs might ignite padding 38, or cause other damage.

The present construction permits access of sixty to seventy per cent of secondaryair, which supplements thirty to forty per cent of primary air fed to the mixing chamber which is highly eficient, and yet does not require a blower system. The lower end of each stack i2 1 is about even with the center of the main roll, which gives a good movement of cold air in at the bottom of the roll, the hot fumes escaping from the upper half of the roll.

The burner pipe may be positioned where desired, depending on the length of flame jet, etc., but I have found that in the embodiment shown the burner may be below the. axial line of the main roll, giving a long, atmospheric type flame. This has been found to be better than the short, blue flame sometimes used, and the roll may be operated at a somewhat higher speed. It can be more easily thermostatically controlled without blow backs, and has a wider throttling range.
